This is a convenience wrapper around <VirtualizedList>, and thus inherits its props (as well as those of ScrollView) that aren't explicitly listed here, along with the following caveats:

Internal state is not preserved when content scrolls out of the render window. Make sure all your data is captured in the item data or external stores like Flux, Redux, or Relay.

This is a PureComponent which means that it will not re-render if props remain shallow- equal. Make sure that everything your renderItem function depends on is passed as a prop (e.g. extraData) that is not === after updates, otherwise your UI may not update on changes. This includes the data prop and parent component state.

In order to constrain memory and enable smooth scrolling, content is rendered asynchronously offscreen. This means it's possible to scroll faster than the fill rate and momentarily see blank content. This is a tradeoff that can be adjusted to suit the needs of each application, and we are working on improving it behind the scenes.

By default, the list looks for a key prop on each item and uses that for the React key. Alternatively, you can provide a custom keyExtractor prop.

Methods

scrollToLocation(params: object)

Scrolls to the item at the specified sectionIndex and itemIndex (within the section) positioned in the viewable area such that viewPosition 0 places it at the top (and may be covered by a sticky header), 1 at the bottom, and 0.5 centered in the middle. viewOffset is a fixed number of pixels to offset the final target position, e.g. to compensate for sticky headers.

recordInteraction()

Tells the list an interaction has occured, which should trigger viewability calculations, e.g. if waitForInteractions is true and the user has not scrolled. This is typically called by taps on items or by navigation actions.
